elle 'cool provi-led il t) threads being avoided. The spindle isprovided with a head 12 to enable it to be Irotated and above the samewith a heavy removable cap 13 provided with relatively yielding material14, as liber, for contact with the end ol' the spindle, the purpose ofthis cap being to prevent the end of the spindle from being upset. Theother end of the spindle is provided with a removable terminal 15 whichmay take any one ot' several lerirs and is preferably provided withrelatizely yielding material as fiber, as indicated at 1G, in contactwith the end of the spindle.

At each side of the spindle S. and body 2 ai'e mounted rods 17 which arefreely movable endwise through blocks 18 and whosel effective length isadjusted and maintained by the nuts 19, 20 located respeetirely aboveand below the said blocks. These rods whose function is ordinarily toexert a pull are provided with removable terminals 21 which may be ofany of the forms shown or of other desired character. 1t will beunderstood that in the use of the tool the terminal 15 on the spindle 8presses against one part of the work as, for instance, the end of ashaft and that the terminals 21 are in contact with other parts of thework as, for instance, the under side of the wheel or gear to be removedfrom the shaft. The turning of the spindle would thus result in theremoval ot' the wheel or gear from the shaft and if the parts were avery tight lit, they might be jarred loose by striking the cap on theend of the spindle, the spring 11 permittingr the spindle to more withits nut. Where the work might otherwisefbe marred, the terminalsnniy beprovidedwith comparatively soft material as liberin the manner indicatedat 2Q, Fig. 1.

1t is obviously important that the rods 1T should be readil' adjustableand I have ar- `anged them so that they may take up any position withinthe total range of adjustment and that they may do this automatically toaccommodate work of different sizes and in accordance with the straip onthe rods. the' rods thus linding their best position without thenecessity of manual adjustment b v the user ot' the. tool. Theconstruction which makes this possible is illustra ted clearly in Figs.3 and l. the blocks 1S acting as there shown as trunnions extendii gacross the slots 3 of the cross-head and having` in their ends cavities23 in which are located spiral springs Qt, the outer ends of which arein contact with opposite faces 25 within the cross-head between theledges 4 and t. rThis arrangement wauses sufficient friction on saidfaces so as to hold the trunnion blocks yieldingly in place at any pointin thc slot 3 and the trunnions permit each rod to turn around the axisof its trunnion. Furthermore, sutlicicnt play is permitted between theends of the trunnions and the faces l5 and'betwcen the springs 2l andthe cavities 2B in the ends of the trunnions so that the ods may alsoturn in an v other plane, the result being an eifeetive universaljointe, 1n the construction shown. the movenient of the rods is limitedby the width of the slots but is quite sullicient for the purposeintended. The fact that the rods i7 may be adjusted without turningr bymerely nninipulating the nuts 19, 2O makes quick adjustment possible andthe arrangement of the trunnion blocks and related parts insures thecorrect location of the rods automatically in accordance with therequirements of the work in any given case.

In `Fig. 5 the tool takes the form of a inachine having the bed plate 2Gsupported hy the rods or legs 27 which may be secured to the floor byfeet 28. -The rods 1T are screwed into the bed plate 26 when the tool isused in this way, the terminals 21 having been removed for the purpose.The tool :ia'y then be used as an arbor press.

r1`hree different forms of terminals 21 for the rods 17 are illustrated,the forni shown in Fig. 1 being as already stated. provided with thestrip of fiber QL to protect the work,

the form shown in Fig. 6 being in the nature of the double elav' 21 toretain the chain 29 in place as, for instance, when tubing or rods areto be bent or straightened and the form shown in Fig. 7 which takes theshape of a foot 21b provided with concentric corrugations for co-actionwith the work.

1n 'order to permit the insertion and removal ofthe blocks 18 and theirsprings 24; an opening is made at the inner ends of the upper ledges ladjacent the body Q so that the slots 3 are T-shaped at the top. thehead of the T being wide enough for the purpose suggested. It may alsobe noted that the bottoms of the cavities 2B are inclined orbeveled tofacilitate movement between the blocks and the springs. the ellectbeing` on the order of a ball and socket joint. The bottoms of thesaidcavities may be curved.
